Abstract:

TRS Technologies, Inc. is pleased to respond to DARPA's request for cost effective manufacturing of high performance piezoelectric single crystals. The objective of the Phase I program is to develop a cost-effective fabrication process for manufacturinglarge relaxor piezoelectric PZN-PT crystals by the Bridgman method. Currently, PZN-PT is grown by the flux technique; which results in relatively small crystals (<30mm in diameter). PZN-PT can not be grown by the conventional Bridgman method (directlyfrom its melt), because perovskite PZN-PT is not stable at its melt temperature. However, by using a flux to stabilize the perovskite phase in a Bridgman furnace that allows the use of a seed crystal to control nucleation, we will be able to produce muchlarger and therefore less expensive PZN-PT than is currently possible. For this program TRS will develop a solution or flux-Bridgman process with nucleation controlled by PMN-PT seed crystals for the production of PZN-PT crystals greater than 1
